Update: January 2008
One of our readers adds: Hi there, as a relative of Lady Mary Pellatt, I thought I should let you know that the info on your site about Lady Mary dying in Casa Loma is incorrect. Sir Henry and Lady Mary left Casa Loma and were living around St. Clair and Heath Street in North Toronto at the time of her death. So no Pellatt's died at the castle, although their son Reg did live in the 'Hunting Lodge" across from Casa Loma and Sir Henry's coffin did rest there for a day or two before his funeral - although I have never heard of any Pellatt or other ghosts at the castle.
Lady Mary died in the home they bought when they left Casa Loma on Spadina Gardens from a heart attack. Lady Mary had diabetes and had been unwell for years, and the stress (and some said shame) of having to move out of Casa Loma was likely not a help. Joan the curator at Casa Loma would know this, and knows me as I've donated some items to them.
I have found Lady Mary Pellatt's death certificate. Lady Mary and Sir Henry moved out of Casa Loma and were living at 3 Spadina Gdns, Toronto. Her date of death was April 15th, 1924, I believe they were out of Casa Loma about a year at this point, but I maybe wrong on the exact date they left, although it was widely said Lady Mary died of embarrassment at being forced to leave and have their items auctioned away.
Our thanks for this information.
